In 1913 Bohr presented the first atomic model, where electrons orbit around a positively charged nucleus at the centre of the atom. In the case of hydrogen, which only has one electron, the circular orbit of radius rn is defined as: m e* where the reduced Planck constant is 1.05457 103* J s, the vacuum permittivity-8.854 10-12 C1 (N m2), the mass of the electron me-9.10938 1031 Kg and the electron charge e-1.6022-10-19 c. The integer n is a quantum number (n 1,2,3.). The energy of the electron (including kinetic energy and potential energy) is given by: where rn is the orbital radius given in formula (1). In classical physics, an electron in orbit should emit electro-magnetic radiation, loosing energy until it falls down onto the proton. Bohr proposed that the electron can stay in circular orbits at specifically quantized energies without losing energyStep by Step Solution
